Artist said: 【PFⅣ】悲嘆の歩行 大きくなり過ぎた巨竜が居た。 彼は生涯を全うしてもなお生き続けた。 数え切れぬ同胞達を看取り、いつしかその羽根で空を飛ぶことも叶わなくなった。 肥大化した体躯による神経の伝達速度の遅延で知性をなくし、心までもを失おうとしていた。 辛うじて残っていた彼の意識に与えられた最後の使命は ”前進すること” ただそれだけだった。
{Pixiv Fantasia IV} March of Sorrow There was a Grand Dragon who had grown too large. He had fulfilled his life and yet continued to live. Having cared for countless ill brethren, one day his wings could no longer carry him. His swelling body slowed the propagation of nerve signals until his mind was lost, and his spirit was soon to follow. The last command he received before losing his thoughts was simply to "Keep moving forward."
Just to clarify seabook's translation a bit - "The last command he received before losing his thoughts" refers to the last command his conscious mind issued to his body (or lower motor control subsystems of the brain, I guess).
So it continues to walk because the "stop walking command" can no longer reach his limbs, or because the distance between the neurons in his brain makes it impossible for him to think "stop walking"?

This. Bodily commands jumping the synapse to reach other neurons is kind of like a lightning bolt. They're extremely fast, but can only reach so far before it becomes ineffective.
