tl;dr athanasios arrives in shadowclan after being exiled within his homeland, with a full agenda upon his sleeve
It was noon.
"I beg of you, Eutropius, to spare me of this horrid death," Orange luminary focused on Eutropius as the latter's mouth quivered in protest — don't you dare betray me so Athanasios' nearly whispered, nearly shouted at the Captain of the Watch. Sweet brother, stay close! I must impart upon you a secret ... The flame remained kindled within the fallen prince as a savage desire of freedom — through any means necessary — overwhelmed him, snarls catching within his throat and an inhuman request of his brother's blood shed by his very own teeth. "Have ... have I not suffered enough?" he asked to deaf ears, closing his single eye and expelled a sigh, recalculating how to get on his brother's good side.
After a moment of silence, the Captain replied a simple "No" and it sent the heir into a fit of rage. Lava fell from his lips as curses threatened to escape, "Who put you up to this?" Tears, hot and on the verge of spilling, were on his eye, and his nose was running. But he knew the answer to his question: The High King and Queen, his parents, their parents. Athanasios could feel their sire's cool breath upon his neck, their dam's glowering face watching for another mistake. Their souls will be mine! "Eu, brother! Please! I have repented, I know of my vices, just let me go!" And yet the Captain of the Watch left, leaving behind an embittered prisoner, aware that his brother was spouting lies.
"Exile."
That's what King Daidalos ruled, its what Queen Iokaste agreed upon; his siblings only carried it out. They couldn't allow their valued heir to be disposed of, that was a reckless decision that would turn the commonfolk away from their rule. As Eutropius and Hagne tossed him to the wilds to perform the deed, Athanasios ran, fire scorching the trees in his wake, a promise upon his lips that sang to the wind: I will take what is rightfully mine upon my awaited return.
He wandered for days within the shadows, setting small fires to keep himself warm, flying above to scout the mainland. And within that time, he plotted, schemed on how to make them pay: who would be his instrument? Who was gullible to fall into his traps? How and when would he execute it? Those questions repeated themselves within his mind, and he molded himself around it. All in due time.
Presently, he arrived at Shadowclan's border, fire kindling above his head and smoke surrounding his flanks, waiting and scorching.
