Nice work with the lineages
Yeah, I could make a trinkets page. It wouldnt be too difficult, probably just a few tables essentially
Dark gifts kinda go with the general discussion of misc things, so once we kinda work out what to do with epic boons, charms, and other such player aquirable features that dont fit into items and feats.
The optional background features include
Inheritor (as in, inheriting a legacy. Depending on the reputation and awareness of said legacy you can shift around public opinion with you),
Mist wanderer (More setting specific, but it lets you recognize Mist Talismens from the domains of dread),
Spirit medium (Advantage on knowledge checks regarding spirits and the afterlife. You also get a free divination tool such as a tarroka deck or ouija board which you are proficient in, allowing you to divine information),
Trauma survivor (Your character is generally knowledgable in how to avoid said circumstances and recover from dangerous ones. People are also generally sympathetic to you)
Traveler (Similiar to other 'You can find shelter among locals' background features, with the additional ability to instantly recognize if an object is from your place of origin)
Hm, however, I do believe we'd need to work out something new for optional background features. Perhaps a page thats part of the backgrounds section titled just 'Alternate Background Features' which has all the features within
Ah! Seperate thing, but Survivors! Survivors are mini classes/statblocks that are designed for players to use, similiar to sidekicks, and designed kinda with the idea in mind that the characters will probably die. Im creating a page for them, but yeah, its interesting to note that survivors and sidekicks exist in a similiar place in terms of miscellany
