The battle caused by Eldrian's shenanigans

Eldrian woke a few minutes later, on the other side of the wall with the sounds of war in the air. A moderate headache kept him from moving fast, but it wasn't anything he hadn't dealt with many times before. Though the throbbing pain on the forehead was new. 

'Oh... Right, that was dumb.' Eldrian mumbled as he struggled to his feat and realized what had happened. He did his best to push down his embarrassment and turned to observe the battle instead.

Multiple holes were now in the wall, a few of the 'towers' were also destroyed. However, it seemed like things were under control. 

The mages whose wooden structures ('towers') had not been destroyed were focusing on crowd control. Spreading fires to limit the undead's paths and strengthening other parts of the wall to stop more holes from appearing. The soldiers instead filled the gaps that were already there.

Reinforcements were also arriving disorganizedly, but constantly.
