I've recently dabbled a bit with Ultimate Magic for Pathfinder RPG and found the optional rule for "Words of Power" as a replacement or complement to usual spellcasting (this concept was already introduced in Ultimate Arcana for D6D 3.5, or possibly sooner).
Now as you've probably guessed by now, I got the idea to use Dovahzul words instead of the abstract concepts presented in the book. As a cherry on top, Words of Power in PFRPG function similarly to Rotmulaagge - a spell is constructed of 3 words (though the 3rd one is optional), and upon utterance they spring into effect.
Now for copyright reasons, I cannot copy-paste the entire list here, but it can be found here.
My idea is that we eventually pair each word on the list with a word in Dovahzul and make a combined list here for ease of referrence. Initially this will likely be just browsing the dictionary and pairing them, but eventually it will almost certainly lead to coining new words to fill the gaps.
If we succeed, I would also very much like to start an online session on this forum using the fruits of our labours. :)
