RPG 2 – The demons are coming!!!

you rushed into a rather large cave, and the dogs were already on your heels... Turning the corner, you see a Dark Elf outpost in front of you... But the beasts are already too close. A broad head opens its mouth to snap at the knight, but a dull sound of air being torn apart rings out, and one of several crossbow bolts hits the dog. The darkness of the cave is illuminated by dozens of thin, purple streaks, and the wind rushes around the squad and the pack of hounds.... The hellish creatures turn into a salad, and several glowing blades of red-haired Furies are pressed against the throats of the swift travelers....
The captain of the garrison rides up to you on his Lizard...
What are your actions?
