1) All Contractors begin with the Condition of Umar's Sight, which gives them the ability to see holes in The Curtain.
2) Native Contractors may not begin with the 'Gifted' asset. Characters who start with this World as their home are human (or mostly human; some inhuman ancestry is definitely possible). This means that some character concepts are just not possible with The Tattered Curtain as their starting home.
3) Visiting Contractors with Gifted are allowed, but be warned that the welcome from the locals may not be the friendliest if its easy to tell you aren't from around here, and relocating here comes with a lot of risk.
