Lith pointed at the Golems and Ragnarök, lingering on the latter longer.
Trouble and Raptor were the only working applications he had found for memory crystals. They granted the constructs part of Lith's bloodline abilities, spells, but most importantly, his wits.
By retaining a sliver of his consciousness, the memory crystals granted the Golems the ability to improvise instead of following a precise pattern and to learn from experience.
On top of that, due to the link with Lith and between each other, the constructs could share the acquired knowledge and improve faster. Being a novice with Creation Magic, Lith was afraid that once recycled, the Spirit Memory Crystal would lose both his energy signature and the stored memories.
