What happened with the Blood Sword books was they were originally meant to be written by me and Oliver together. But while I was a full-time author, Oliver had a job at Transworld Publishing (publishers of Dragon Warriors) and his workload began to mushroom, with the result that he had to back out after doing only about 25% of the first book, The Battlepits of Krarth. I then wrote the next three, but we always intended that Oliver would clear enough time that we could partner up on the finale of the series, The Walls of Spyte. Unfortunately, after drawing that first map and writing about half the book he had to drop out owing to a combination of career and personal pressures. That's why Jamie Thomson jumped in at short notice to help out with a couple of hundred paragraphs.
The Blood Sword books are probably quite hard to find these days (legally, anyway) but the first three were turned into my Chronicles of the Magi novels, available as PDFs for $4.95 each on DriveThru. Again, not strictly canonical Legend, but useful for roleplaying in Krarth, Wyrd, Outremer or the Ta'ashim lands. This taster should help you decide:
The heat of the day had long since fled from the desert, and under a sky of a million stars a man stood on the white sands beside a corpse.
In the man’s hand was a long knife, gently curved, whose blade shone dark and wet in the cold moonlight. Stooping, he dipped the knife in the corpse’s gaping chest and used its own blood to draw a circle around where it lay.
The task done, he raised his eyes to the heavens and spoke seventeen syllables in a guttural tongue.
A wind rose, pulling ripples of fine sand across the moon-bleached dunes.
The man directed the knife in turn to each point of the compass, his movements as graceful and precise as those of a dancer or a beast of prey. And as he turned he seemed to sing a spell under his breath in the same exotic language.
At his feet, the corpse’s eyelids rolled open and it stared in blind horror at the stars.
