So I am building a village and I decided to give them a displacer beast problem that has existed for the villages entire history; however, upon doing research I can't find basic information about them such as natural lifespans. Looking into other monsters and beasts, I run into the same problem.
I want to try and build a realistic problem for this village and I need to know for example:
- How many baby displacer beasts per pregnancy?
- How do their mating cycles work?
- What are the natural lifespans for them?
- Do displacer beasts have dens? If not, what kind of shelter do they prefer?
I notice this same problem occurs for most if not all non-player races in D&D. While this question is focused on Displacer Beasts, information about a resource that covers more would be helpful.
