The Dwarves and their allies had been driven deep into their stronghold but in their territory they managed to hold back the enemy. At the battle of Kalders folly the dwarves met the full host of Svirfnebli in the hall of Ancient Drums. Using their knowledge of masonry combined with a Galanodel contraption they planned to lure the Svirfnebli vanguard into a trap thus crippling the army. Unfortunately the Svirfnebli psions used a trick similar to the that which won them the battle of the red pillars. They used a dominated dwarven spy to trigger the trap early causing several tons of rock to be blasted out of the cave wall on top of the dwarves own leader Kalder the VII who’s idea it had been in the first place. After this loss the resistance scattered and escaped into the deep caves.
