Tolkien fan-fiction that is. Not that I have delusions of grandeur; far from it. My approach is one of respect and sense of adventure: to understand and fill in the gaps unsaid (mainly to calm the unavoidable mental fidgeting in my head), not reinvention or re-imaginings – which is as fruitful as trying to re-discover the wheel, or fire.
Canon-friendly, canon-correct, canon-conscious, whatever the term, those are my perimeters, my prime directives. Which can be personally stressful and painful, painstaking in fact.
