Godwyn thought he was all set. He had a comfortable cave with a magical aura, a basic laboratory, even his own grog. What he wanted next was a Talisman. Assuming the form of his heartbeast carried with it a major inconvenience: his clothes don't transform along with him. Godwyn wanted to enchant a set of clothes and then attune the suit as his Talisman, so it would by mystically linked to himself and would change form along with him. To do that, he needed raw vis.
The tome he "acquired" from a monastery the previous winter spoke of a forest called "the Weld" in south-west England as a magical place. So, he and Thomas set out in search of it. Once again, they got lost, but Godwyn was coming to accept this as an inherent feature of any long-distance travel.
