World Adjacent to Earth:

Rustic: Basically everything but projected force doesn't work (including high tech). effectively TL 3, with a decent amount of emigration from other worlds. Protected by highly skilled knights. Celtic is dominant, with some Demonic. Notable for bordering on demon territory.

Magus: No mental magic. Native mages are skilled with TK, fire, and other brute force magic. The land is mostly run by bureaucrats, and home to a large number of flying creatures: griffons, (small dumb) dragons, hippogriffs, and so on. Ancient Chinese Dominant

Legend: mental magic works. Solid magic insubstantial does not. Lots of city states and small, organized kingdoms.Currently sent into chaos by Earth showing up. Egyptian, and Pharsee dominant.

Barren: Rock ball with fierce winds and no oceans or rain. Air is somehow breathable. All magic works except for that which creates minds or life.

Voyage: No Communication magic works. Mind magic requires touch. Lots of small islands, merfolk, intelligent giant lobsters, seals, and bird-people. Storms and islands have powerful guiding spirits, large sea monsters exist. Human population speaks with spirits to survive. Earth struggles to navigate local politics. Mayan among spirits, Sanscrit(accented) among native species, local tongue similar to (Broken level) Polynesian among humans.

Elf: Spirit Insubstantial doesn't work. Until recently, elves ruled this mostly human-populated planet by virtue of ageless warriors, superior metal-work, and mind-affecting stones (some affect large areas, some protect against the effect for one person). Recently a number of Earth-sponsored revolutions have tipped the balance. Humans here speak a variety of languages, most derived from Demonic (accented to no default).
