Glassco grumbled to himself.
Take rock from the surrounding area as needed if more materials are needed so as to maintain proper integrity.
First, turn the bowl into more of a ship shape, kite-shield like or tear drop like, whatever shape ships usually are in when viewed from a bird's eye view, that shape. Normal ship shape.
The ship will have a deck not too dissimilar to decks on normal ships, although it will only have one level. The floor of the deck is slightly convex, fitted with grooves which is to help along the water off the deck as well as to increase traction on the floor so it would be harder to lose one's step. On the edges of the deck is a waist height wall complete with guard railing. The bottom of the wall however has rectangular slits so as to allow water to flow off of the deck without catching anyone's foot however. As in a person's foot can't fit through the slit, its just meant for liquid.
The ship itself should be about two person's in height, three in length, two in width. So roughly ten to twelve feet tall, fifteen to eighteen feet long, and ten to twelve in width.
On the main and only deck should be a trap door made of a thinner stone than the deck with a handle on it that reveals a hollow interior. The walls of the interior still being rather thick however, mind you. Inside the interior there should be just enough room for someone to stand, and laying down if laying in the right direction. Inside this room on the left side is a low raised stone rectangle that is to serve as multifunction cot/table, and two knee-height stone slabs with backs to them to serve as chairs, on the other side wall, facing towards the cot. On the front ends of the ship, there is a shelf that cuts the 'V' shape ending in half horizontally, so as to allow for more efficient cargo keeping. In the back however, nothing, to allow for larger crate/cargo storage.
Back to the outside of the ship: On the sides of the ship, below the hand rails and walls, are six very thick but close to the hull rings that are specially made for Sparky's manipulators to grasp onto, it will be grooved with bumps and edges, both the ring and the wall near the ring, to allow for greater grip. The horizontal slits in the walls made to make liquid flow off the deck of the ship are positioned and grooved in such a way that water won't flow on the rings or the walls around them, so as to ensure a proper, dry grip.
On the front end of the ship, there is an image of a spear made of bones from a hand, with the fingers fusing into a point. Around the bone spear a spinal cord is coiling around it ending in a skull. The spear is going into the skull and out of it from its mouth The skull is laughing.
On the back of the ship, there is an image that in it there is a vague impression of a person in a plain white mask, the mask being the only defined part of the person, standing on top of a giant beetle not to dissimilar to Sparky. Lightning striking around them, converging into a single point as if controlled above the man into a splayed hand. The person is triumphant.
On both sides of the ship, there are words written. They say Terra Ascendéntem in fancy, but easily legible script.
