They will try to make a secret attack on the gods. But Heimdall, the sentry of heaven, will be on guard at the end of the rainbow-
bridge. He needs no more sleep than a bird and can see for a hundred miles either by day or night. (He will sound the horn
whose blast can be heard through heaven and earth and the under-world. Loki and his army will be seen by him. His loud alarm
will sound and bring the gods together. They will rush to meet the giants. Woden will wield his spear-Tiew his glittering sword
- Thor his terrible hammer. These will all be in vain. The gods must die. But so must the giants and Loki.
