At which point the Old Ones warm the world then do their "reshuffle the continents" thing, which requires breaking the crust into plates, and hey presto!Water is also an important factor in plate tectonics. If the bulk of water on Mallus arrived after the planet itself was fully formed (by say comets) then despite the abundance of (frozen) water on the surface the mantle would remain dry as the main mechanism that transports water from the surface to the mantle, subduction, requires plate tectonics in the first place, a kind of geological catch-22.
