The Hollow Rider – Live on New Legacy!

Posted on by UO Dev Team

10/30/2026 Greetings, The tales from Yew were true. Each year on the last night of harvest, the farmers of Yew lit their lanterns, and the hoofbeats passed them by. But this year Britannia burned brighter than it had in an age, and that light drew something out of the deep woods. Now the fields outside Yew are ringed with fire. Pumpkin-headed shapes shamble between the trees, and at the heart of the flames waits a rider on a burning horse. He has a blade in his hand, a pumpkin upon his shoulders, and he is searching for the head he […]

Posted on by UO Dev Team

10/16/2026 Greetings, We are pleased to announce our next Weekender Event, The Hollow Rider, will launch October 30th, 2026, exclusively on the New Legacy Shards! Strange tales are drifting out of Yew. A shepherd swears he heard hoofbeats on the forest road, though no horse was there.

A woodcutter speaks of a rider glimpsed between the old trees, sitting tall in the saddle and somehow wrong in shape. He couldn’t say what was missing, only that the longer he looked, the less […]
