Ilshana comes around to stand beside, and a bit behind, the other man there, and begins humming a strident tune like a marching battle hymn. Ghostly figures materialize around her, with horned helms and straps of leather bearing massive metal studs and shields that they thump in time to the rhythm. They started hooting and chanting along with her...and as the song reached its crescendo, they released as one a titanic 'HUAH!' that blasted forth with physical force!
In the rush of wind and noise, the phantom figures blew apart like the dreamlike memories they were, and Ilshana was revealed! Mindful of this revelation, she quickly retreated a bit more. The old elders of the barbarian clans might roll their eyes, but they were DEAD, and Ilshana had no intention of joining them just yet!
(Move to DH154 and cast Thunderwave north, cornered a bit to leave my pal there out of the area, at 3rd level. Axebeak and orc need Con saves at DC 15 or take [roll0] thunder damage and are pushed away 10'. Half damage and no push on success. Then she completes her move to DH157)
