You're Welcome On My Boat
Ulphamero is an rim world that should really be classed as an uninhabitable planet of mostly rock and magma. For some reason though, a fair few scientists have landed a bio-dome there, thinking that something in the planets core could help humanity get accustomed to the heat. Whatever it is, it’s dangerous.
Alongside the heated surface, there are a number of metallic lakes around the planet, huge amounts of mercury. Inside are some Pokemon that have strangely adapted to the liquid, including Metallic Muk, Tentacool and some rumours of a very interesting Onyx.
Strangely, a number of Unown came to the crew before they were landing on Ordona, and spelled out some mysterious words which seem to have some relation to Ulphamero.
