Collector

 is an NPC vendor that will spawn once the following conditions have been met:


 * There is an empty house.
 * The Spirit has been defeated.

When threatened by enemies, he will defend himself with Star Wrath projectiles.

Exchange
Genoshi will exchange some special items for something else that can be turned to either an accessory or a weapon. If you have these special items the Exclamation point will pop up above his head. Also, items (that you can give him) have a note about it in their description.

First Quote

 * "Well well well, what do we have here? So you're the one who Spirit's buzz about. Man, you're a mess! Apparently teleportation wasn't entirely successful, just look at you face! Well, enough about you. I'm here to help you with your dangerous journey. Have you heard anything about the elements? Find them all and we'll see what we can do."

Always

 * "Oh, Spirit... she told me a lot about you. I'll tell you by secret - your fighting style greatly confused her."


 * "Do you know that on the Nexus I was appointed as a Keeper! Sounds awesome, right? Although I never understood what I was keeping, but.. I'll figure it out somehow."


 * "I'm sorry, but I'm not ready to show you my entire assortment at once. You have to be responsible for the power that will be granted to you. Seriously, I'm watching your progress."


 * "Sorry for being blunt, mate, but I thought you were taller."


 * "Spirit... she still regrets that she attacked you. I told her that new students can be sent in the Terraria, but forgot to mention that they can possibly be humans... She just haves some.. personal 'problems', associated with humans."


 * "You know, being a collector of pretty difficult.. especially because of the temptation to sell all collected. Fortunately, you can help me in this. If you find something interesting, bring it to me, and I will exchange it to special weapons and equipment!"


 * "In this world, there are strong creatures that guarding a large number of elements. You get them if you can defeat these creatures, but alas, the subsequent battles will bring much less profit."


 * "Forgive me if I am.. slightly obsessive in my proposals. Do not misunderstand me - your path will be difficult and I want to help you, but I also need something to live. You help me, I help you, all to be honest!"

When Dryad is present

 * "Well, Dryad told me about her adventures in Eternia. I don't know why, but it looks like she misses those days."
 * "Yeah, a lot has changed in my absence. Except the Dryad - she is still grouchy."
 * "Ugh, just tell your Dryad to stop showering me with her purification powder."
 * "Hey, this Dryad of yours looks like a big deal... But shouldn't there have been hundreds of them, where's others? I remember exactly that there were more."

When Angler is present

 * "Sure there aren't any smart people around here, but I like [Name of Angler]. He's a tough guy and he clearly knows more than anyone in this world. No wonder he has so many fans."

When Travelling Merchant is present

 * "Do you know this 'travelling merchant'? I think his name is [Name of Travelling Merchant] ...Forget about him. This guy always tries to find something worthwhile, but he generally finds junk. Though, to tell the truth.. those cloaks were really good."

When Tavernkeep is present

 * "I have to say, it used to be much quieter here. No anomalies, no travelers from other dimensions. Look at this tavernkeep guy. He doesn't even remember how he got here! Not world, but a public thoroughfare..."

When Librarian is present

 * "You should be more careful with that.. librarian. It seems to me that his ordinary appearance hides another interdimensional traveler.. Or it's just a regular merchant.. Anyway, keep your eyes peeled."

When the Troublesome Vessel is in the player's inventory

 * "Oh, what a wonderful bucket! Spoiler alert, there's an Element of Fire inside. Won't deprive you of the pleasure of finding a way to unlock it, of course."

When 'Wanted- Oscar Loneshot' is in the player's inventory

 * "Ah, that face again.. Haven't we talked about him already? Yes, he was a scientist, known for his stupid inventions, like the jet-slippers, or whatever that was, and everything was fine, until he began to steal resources from my fund and used forbidden technologies, which led to countless deaths in the interdimensional shipwreck! And guess who had to deal with all this madness? Okay, just... get it out of my sight. We have a lot of work ahead of us."

Lore

 * "Huh, me? I'm has as much a traveler as you are, except I have my own personal palace, tons of subordinates and lots, LOTS of money. Don't worry, it'll all come to you someday, too."


 * "Huh, the Nexus? You really must been living in a cave, if you haven't heard of it. Okay, in plebian terms, the Nexus is a place where heroes from all over come together - merchants, scientists, architects... All those who have decided that their own world is not enough for them. Well, it's also a convenient excuse for all these weird characters to come to your world."


 * "Huh, the Spirit? She's just my ward, she was tracking anomalies in your network and helping me find some villain. I don't know what suddenly prompted her to go on a mission alone, but I'm not worried about her, she's found the right world after all. I even wonder how she's planning to get out of this mess."


 * "Huh, the I.D.E.A? It stands for Inter-Dimenstional Emergency Agency, don't mind the abbreviation, I don't like it myself. The idea is... oh, that's why. In short, the agency was formed to prevent users fr overflowing their world with lots of modifications, as this can disrupt the sequence and totally kill the experience from each individual project. You know, since Spirit sitting behind the director's chair, no one cares much. Well, you got the idea."


 * "Huh, the sand people? I'm surprised you're interested. Anyway, the majority of the inhabitants of the Nexus belong to mineral-based life forms. I know it sounds ridiculous, but due to our structure, we can handle teleportation much easier, which is especially important for travelers between distant world's. One of them is standing right in front of you, and you're already met Spirit, and... I hope you'll never met the others."


 * "Huh, the transmitters? Before one smert guy invented the PDA, travelers used some kind of 'magic mirrors' to bend space and time. But we've taken this concept further and can now travel between different worlds! Recently i gave the most sophisticated transmitter to Spirit, and she's already magaged to break it! Ugh... You don't even imagine how it's hard to get a transmitter suitable for her sizes!"


 * "Okay, I guess I've reached the limit of my amazing and fascinating stories. If you don't understand anything, it's even better, it'll be easier to work with you. And if you don't have anything to do, I can repeat it all over again. You've got so much time, don't ya?"
