The Legend of Sol, Titan, and Morgan: Canterlot

In myth and legend, the city of Canterlot has always welcomed Sol, Titan, and Morgan with open embrace: but the truth is not quite so generous. No, in truth, it was a very cold welcome that the three received, along with all the warriors they had brought with them.
The Holy Order, at least, had some presence already here in Canterlot: it allowed them to find a small bit of sanctuary... although that did not extend to their other fellows. They said the rules of their order forbade them from welcoming even their leaders onto sanctified ground, unless they took a vow of faith. Sol did not press the issue, however: she knew the real reason for their attempt to stay aloof, and it did not bother her. But it was all the same a piece of information she would file away, and that would later come back to haunt this once so-proud order.
Titan found his way to the smithy, and soon found himself a place to work. He invited his sister Morgan to join him there, and for a time she did. She enjoyed herself, but it was monotonous, and after only a few days began to grow boring. But it was better than staying with Sol, who had found herself a roost in the great libraries of Canterlot.
It was strange for all three of them, however, to have settled into a place: to not just be making camp, but establishing what could almost be called a home. They all did their best to keep busy, but it was a different kind of busy than being on the road: there was no need to hunt or prepare rations, there were no trails to blaze, the scenery around them changed, and yet remained more the same than it ever had.
All the same, they were determined to make the best of what they had here. Sol had great plans, but they required patience, and they had much work to be done before they could leave... and part of that job was making sure that this place became like home to them. It was difficult, with how uneasy the Baron and his people were about the strange ponies that had arrived... but all the same, they were making slow strides forwards, in large part thanks to the fact that Sol was ever reminding her siblings to be patient, and to behave themselves.
But as Titan worked at the smithy, and Sol began to help out more and more at the library instead of keeping to herself and her own research, and Morgan became a common sight around the bars and brothels and throughout the city, the three became known to the ponies of Canterlot. Titan, ever industrious, happy to lend a hoof to even the meanest pony in need without asking anything in return; wise and powerful Sol, who knew things that made even the oldest mage feel as awed as a child in her presence; Morgan, the adventurous and strong, whose exploits made the youthful laugh and the old shake their head in disapproval... and perhaps longing, for the days when youth was able to wash out the stains of foolishness and brashness.
And so their life continued, developed into something more than just an endless journey: so Sol, Titan, and Morgan found themselves a home, a place where they could stay, a place where they began to be accepted, and perhaps even belong.
Until one day, the Baron summoned them, for he had a request.
