This is a new The Elder Scrolls V: Skyrim Mod that will add a unique piece of Stormcloak Officer Armor to the game.
After the attack on Helgen many bodies will never be recovered, eaten, burned to ash to lost in the rubble of the city. One of Ulfric Stormcloak's personal guard stayed behind to cover his retreat, but was snatched up by Alduin and thrown clear of the village. His badly burned and broken body landed in the river just west of Riverwood where the rapid current dragged him further down river.
Being one of Ulfric's personal guard he wore a unique set of Officer Armor. This mod places his corpse somewhere in the river between the Guardian Stones and the waterfall east of Riverwood. Keep an eye out as you walk down the path and you may see him.
