Shutting the Eyes
Heimdall stood his vigilant watch at Bifrost, surveying anything that could be of danger to Asgard.

"What's this?" He saw a figure approaching something of great importance. He looked harder until he could identify the man. It was one of the Ennead, Seth's wretched offspring! What was he..? "No! I must tell Lord Thor immediately!"

However, before Heimdall could even move, a massive, cloaked figure suddenly appeared in front of him.

"Your eyes must remain shut, guardian."

Heimdall went to strike but was suddenly overcome by a blast of cosmic power. Heimdall fell, his skin burning. "Must..stop.." but the pain was too much for the warrior, and Heimdall fell into unconsciousness.
