The Floating Tower was actually very fragile.
At least until they understood the core Energy Protection Field used by the Floating Cities of the Arcane Empire, the Floating Tower's current defenses were roughly equivalent to a wide-area Level 6 Energy Abjuration Force Spell. Defenses of that caliber could probably withstand only one full-force blow from Soren in his deity form, or a few attacks from the Githyanki.

"And now..."
"It seems an enormous hunk of iron is heading toward us. Judging from the materials at first glance, all of this is forged steel mixed with astral matter and given basic
