From the great podcast The Aventure Zone! This is how I always envisioned the Starblaster, the ship built by the IPRE to travel between planar systems. From the description and my own time playing DnD I always envisioned a heavily modified sailing ship combining magic and technology.
This is how I imagine the ship being towards the end of the Stolen Century arc. After nearly a century of being lived on the crew has added a few features and made some changes to the original design.
