RPG I: The Necromancer's Revenge

Two dozen ghouls??? Ugh, I should have spat and rubbed it! So, one more time, I need to... put them all to rest there??? Then show me where this temple is, and I'll be on my way.

Alright, here are 2 guards to help you. You've arrived at the temple, or rather, you are 100 meters away from it. You can sense the presence of mages, dark ones, probably 2 liches. What's your next move?
