Looking for some books that include those themes for inspiration:
\- Vast and complex world building (including history, different species, astronomy, past events, original mythos)
\- Medieval/Dark Fantasy
\- Multiple protagonists/divided protagonism
\- Absurd/Lovecraftian like creatures, entities and gods
\- +18 (without excess though)
\- Inclusion of both plain and in-depth characters
