Marching was good, he could march, he couldn't charge or sprint but even his 'blessed' legs could keep a stock march with everyone. He'd ride on wagons when a rotation was offered if even it meant he put his 'cane-ga-rue' feet on the back board and latched on with his weaker upper half to ride and bump along so another could ride in his spot. Usually it was his favored female who returned the kindness later in one way or another.

When the keep was met, Shar did his best attempt to scout using his gods blessing. Concentrating the power of the titans, he levitated up to the highest point he could hold onto such as a tree from sixty to a hundred and twenty feet then back down again before drawing what he saw into the mud for another who was better at transcribing what he saw. He presented the sketch of the area to the leader with the focused insight of his time dealing with churches.

"If the keep isn't finished being built, then the church is acting as the temporary fortress until it is finished. Stone walls, huge open main area to seat the entire village at once with benches to brace defenses at a moment's notice, tall thin windows used as arrow slits, solid double doors, tall lookout bell-tower, basement that can turn to mausoleum/catacombs but for now can hold almost a full years food and water. These are standard features of any bunny's church. 

Even if we get over the walls, they can hole up in there for weeks. If we can get some shadows up over the wall it would be best to get them in the church from the tower and let them gut it from the inside out to take away their fall-back. as for the big fight, send some mucked-up diggers with tower shields to cut out the ground at the top of the hill at the foot of the fort, let's let the dirt ramp work for us to take out some of those logs in the wall and pour through. If the logs fall, we got bridges and ramps for us to march up."
