The Unicorn Gate

KOMACHI'S TRAVEL GUIDE:

When the Unicorn returned, bearing their many wondrous treasures from abroad, they found Ryoko Owari a welcome home for their merchant enterprises. They quickly established this as one of their most favored locales for merchant patronage, building an impressive residence and offering to show their friendship by building a new gate to the city, and connecting the Scorpion's provinces to their own by a new road.
Sadly, no pass could be found through the mountains to their lands - but the gate they built is a wonder, flanked by pillars of gold-flecked purple stone.
The Unicorn say those pillars were carried over a thousand miles to reach Ryoko Owari! Stretched across the top of the gate is a thick polearm twenty feet long, captured from one of the many monsters the Unicorn Clan found in distant lands. The doors are made of an exotic white wood, carved with scenes of the Unicorn clan's foreign adventures.
