Excellent vibes! An impressive quality of voice acting given the short time frame (especially all done in one afternoon, wow!). The layering effect you've managed with the voice lines definitely conveys a being of power and mystery while still retaining comprehensibility - I've played AAA games trying to convey the same feelings in the audio that have done a worse job at it.
The writing was atmospheric and believably archaic-sounding while nailing an interesting tone and subject. Great work!
