Game finally comes together

Been GMing an AD&D 2E game every other Sunday now for a few weeks and it seems like everything clicked last night. The campaign is set in a world in the midst of an ice age. There are two human empires, the Vikings and the Romans. But they are being pushed towards the equator by the unusual cold and the Humanoids. Orcs, Ogres and Giants are the main lifeforms on the planet and they want the humans, elves and dwarves exterminated. The Roman capitol was squashed in a war with Dragons on the eastern side of the world. The Vikings and the Dwarven communities co-mingle a great deal in the West. The Elves are more numerous to the East with the Roman Empire but they do not like to mix. The Viking dieties keep a close eye on their human followers, while the Roman gods are getting more and more hedonistic. Odin wants a good battle, while Zeus just wants a good time.
The characters started out in a viking boat together, traveling north across and inland sea, much like the Mediterranean but Much colder. They were all given a dream sequence, by Bragi, of a village being raided for souls by a giant army. In the morning, they found the village had been sacked sometime ago and was mostly a shell. They skirmished with some orc looters but did not manage to kill them all. The ones that got away warned their brethern in a watchtower some distance away. The PCs had a running battle with the Orcs as they made their way to the watchtower. They managed to draw out a large group of them and squash them. Taking the tower was a very near thing.
Afterwards they traveled on to another fortified village. Along the way they found the Orcs like to send out patrols quite often. Once in the village, the towns people were eager to hear their stories of battle, while the women tried to bed the male adventurers as much as possible. The players found that women in Viking culture are encouraged to have as many babies as possible and consider men their trophies. After some delightful roleplaying the characters decided to travel to a fort Haugr to the north and kill as many Orcs as possible.
Last night the party was visted by Bragi, Thor and Odin. At least three of the characters were given quests with possibly large rewards at the end. The next day, they ran into an Orc work party that was creating a checkpoint. The characters managed to get a small group away from the checkpoint and decimate most of them. The escaping worgs alerted the checkpoint that something was wrong and they charged out to find what was the matter. The bard was able to cast entangle twice and immobilize 2/3 of the group. The party still had a close time of it battling the rest with the head orc in the lead. They had one round before a large group broke free of the spell and managed one last entangle and barely escaped with their lives.
