It would seems most messages turned off-topic here.
But i find pinned topic General RolePlay Guides is pretty useful and very explanatory with all those screenshots and etc.
From myself, i suggest you be simple and not do all this “demi-god, half-orc, half-elf, last of their kind, void-fused person with mechanical arm with bunch of 1st glances-paragraphs” type, especially as your first character.
The more unique, uncommon and mysterious character is - the less contribution this character can make to RP. In my opinion, of course.
Surely, everyone want to stand out somehow, but remember about golden middle, while doing this and be humble.
