In about the Earth year 1780, a new passage was discovered between Earth and another world that was not Elfhome. An explorer group of twenty domana and sekasha were sent through and discovered that it led to Onihida. Blossom Spring was one of the domana and she brought at least her First, Granite. The oni mutilated Granite by removing his arms and right leg. When the oni tried to breed the elves, Granite drowned Blossom to prevent her from becoming pregnant by the oni. Granite later died before he could escape.
Only the domana Forest Moss and the sekasha Silver Vein in Stone, who did not look to Forest Moss, survived to escape the oni and return to Elfhome. Due to discovery of this passage, this and all known passages between Earth and Elfhome were purposely collapsed.
