@TheDarkLord this will probably help with your lore making
Below are all of the valid keywords to ask castaway:
Goblin, erthium eye, mech terror, help, hi, hello, sup, gnome, zombie, ancient statue, the s word and rhino (castaway responds the same as with hi, hello, or sup for some reason), slime, skins, missions, caves, snow, lava, woodlands, big ooze, castaway, futurepear
And finally, if you ask castaway “Who are you”, then he will respond “I forgot”, “Who am I”, or “I was here long ago”
There’s also a glitch where if you spam random stuff it gives you a greetings message
There are more keywords: Jungle, thang, paladin, Erthenton, castaway, bug, chicken, savanna, portal, alpine, taiga, erthium(responds the same as hi, hello, or sup), graveyard, whirlpool(responds the same as hi, hello, or sup), birds, saplet, toadstool, caecilian, spike, grassland, crates, amphibians(responds the same as hi, hell, or sup), boss, and weapon. I am sure there are more.
