Gothic II/The Valley of Mines

After Lord Hagen has given you the key, it's time to return to the colony. As you approach the door, the guards will warn you about the many orcs behind that door.

They're not wrong. There are many orcs behind that door. If you chose to be a fire magician, you now have a Fire Arrow rune, this is what the game gives you in preparation for these hoards of orcs. Sadly, Fire Arrow is completely and utterly useless against orcs. So you'll have to rely on whatever else you've got. Melee weapons, bows, spell scrolls or just take a speed potion and run past all of them.

When you reach the end, you walk into a loading zone that brings you back to the colony. Where you'll find.. more orcs. If you played Gothic 1, the environment is going to look very familiar, but not everything is the same.
