OOC: Right, I have more time on my hands now, so I'm going to set the history of Sandy Castle in context (If that's ok with Y64M)
The Legend of Sandy Castle:
In the time before time, when these lands were dry and barren, there was nothing. No people, no sea, no animals, nothing. Only vast sandy lands, undulating over millions of miles with no visible landmarks. However, this was unappealing to the Council of Deities. "We do not wish to rule over nothing," they said. "We want to fill the hollows with water and cap the mounds with snow." And so, the seas and mountains were created. However, the deities were not so easily pleased. "Where there is no snow and no water, the land is still sandy. We do not wish this to be the case" So they created trees and grass, and covered the remaining parts of the land. However, the Devil was not pleased. "All this life makes me SICK!!" he exclaimed. "All these plants must not remain there forever!" And so he banished the plants from the east of the lands, and created the desert. The Deities were very displeased. "How dare he spoil our beautiful lands," they said. "He must be punished." And so they sealed the Devil in a place beneath the ground, a place called Hell. Then the Council said: "Our lands are empty. We desire subjects to rule." And they created every species that populates the land today. However, the Devil was sly, and tricked a human into breaking the seal that held him captive. "If none of this can be mine," he proclaimed, "then it can't be yours either!!" Nd so the Devil placed evil into the souls of the creatures the Deities created. The Deities were displeased and sought to seal the Devil away for good. However, as long as evil existed in the world, the Devil was tied to it, and so could not be sealed away. But the Deities devised a plan, and tricked the Devil into sleeping by a fault in the rift between heaven, hell and the land. The Devil still lies in slumber there today, apparently.
Now we journey from legend to history.
Sandy castle was originally a temple for the Goddess Janit, built on the seal that bore her mark. She was Goddess of the ocean and the sands, and was head of the Council of Deities. It was built by the nearby Litorian monastery, and monks commonly went there to pray. However, as the two kingdoms which the sea divided got more powerful,the temptation of piracy was too much, and the temple became a stronghold under Abbot Pessim. However, the fortress was under the watchful eye of errant mercenaries from the beginning and only ten years after the monks turned pirate was the fortress captured by Oculus. The fortress was then used as a camp and a stronghold for mercenaries who were not in service or favored the life of piracy. But, only a year before the events of our legend take place, a tribe of Demon Summoners from the north overran the castle with a combination of sorcery and spirits. Their power bolstered by the seal of the Devil, they are nigh on unstoppable. And I'd say we can guess their ultimate aim...
So, I think I've covered all the bases and provided a pretty decent sub-plot. Sorry for the archaic style at the start, I wanted it to sound legend-y...
