So ive found a few blogs of late on a similar idea for super hostile terrain. I want to use such horrible places for my new underland setting in play and for under my islands in the Tenkar's Landing shared setting. Also handy for my Psychon setting. The underland is a hostile remnant land where ancient and prehuman remains have been hidden away and forgotten by surface folk. It is a post apocalypse dark fantasy setting that should be horrible. This post is about the basic terrain. Another will be on citadels. Another on dungeons, ruins and settlements. One on fantasy versions of my citadel generators. Ive foolishly sent my players there so will be pumping out more content.
Light in this setting is dim but present in most cases for at least night vision to function. The are great lights on the tops of some ruined citadels also used as navigation beacons. These artificial lights might be any colour or have colour tints. Some flicker or fade seasonally. Bioluminescant growths are common but surface human vision may struggle at times.
December 18 to jan 8 will in Adelaide with possibly poor net access but will spend time editing old works.
