Improved Illithid Nautiloid -- Spelljammer

This design is largely @RollingNat1s'  Nautiloid that I modified with some elements of @BigAlGaming1's Mind Flayer Spelljammer ship – Nautiloid

I lengthened the design, added a ballista on the bow, and added a tadpole pool. I added a command deck and put a helm throne up there along with an observation bubble. I exchanged the telescope for BigAl's.  I thought about putting a rear sail but I wasn't sure if the slab would be too big and then suddenly it became less important.  Maybe I'll update.

Anyway if you end up using this, throw some credit to Natty1 and BigAl too. This is more their work than mine.
