Born from the impact of Thor's hammer striking the ancient stones of Asgard, Strength's Bastion emerged as a living embodiment of unwavering power. The entity absorbed the essence of Thor's might, becoming a physical manifestation of pure strength that would serve as both protector and inspiration to worthy warriors. The gods themselves recognized this creation as a necessary pillar in the quest for Valhalla, appointing it as a guardian of those who seek to prove their physical prowess.

Strength's Bastion exists as both a physical structure and a sentient force, able to manifest as either a towering fortress of living stone or a warrior of impossible might. It radiates an aura that enhances the physical strength of worthy warriors in its presence, while testing their limits through trials of pure power. The entity can temporarily grant portions of its strength to those who prove themselves worthy, though such gifts must be earned through demonstrations of both might and wisdom.

As a guardian within Thor's Champions, Strength's Bastion serves as both a training ground and a final test for warriors seeking to prove their physical worth. It judges not just raw power, but the wisdom to use such strength honorably, ensuring that only those who truly understand the responsibility of might earn their place in Valhalla.
