When I said thrash around, I meant reach. I thought that's what Shade meant too. Anyone know how big around these tentacles are supposed to be? That might help.
Their illustration in the Immortals Set shows the tentacles as being about one-thirtieth as thick as they are long. Unfortunately, the illustration doesn't match the proportions in their description. The central core in the picture is about 18% of the width, not the stated 10% - maybe the tentacle-mouths can retract?
If the "tentacles" are as thick in the picture, and the core is 10000 feet wide (the stated minimum thickness), the tentacles should be about 900-950 feet thick. The mouth at the end of the tentacle is 2-3 times wider than the tentacle itself, but is wider than it is tall.
That suggests a typical Draeden has a 10,000 foot diameter core, with tentacles 900 foot thick reaching up to 45,000 ft long which end in mouths about 2500 foot wide and 1200 foot tall.
