Rory heeded Skelmis' advice; he waited until he had swum to the shallows of the beach to drink the vial of liquid. Rory regarded the bottle; it was composed of a thick, heavy crystal, like a piece of quartz that had been hewn out of the earth, fixed with a ruby topper. Thoughts flew through his mind at what the potion would do to him. It might simply kill him; it could all be a trick of the Sea Warlock to rid the ocean of one more merman. It might cause him excruciating pain-and then kill him. It could turn him into something other than human; something vile and monstrous and deformed, or a tiny creature, like a button jellyfish.
