I'm not entirely sure specifically what that particular fanfiction is about as there could be many interpretations. It might be a story that involves characters named Percy and Echidna in some sort of fictional scenario created by a fan. It could potentially be an adventure - based story, or perhaps a story exploring their relationship in a unique way.
One common theme is loyalty. Echidna characters often show great loyalty to their clans or comrades in the fanfictions. For example, they might fight to the death to protect their fellow echidnas.
There are also the mysterious and powerful seer echidnas. Their ability to foresee the future and their knowledge of ancient magic make them very interesting characters in fanfics. They can be both allies and a source of conflict as others may try to use or control their powers.
One idea could be a story about an underdog character in the Echidna Wars who rises to become a great hero. Maybe they start off as a simple foot soldier but through their wits and determination, they turn the tide of a major battle.
Fanfiction platforms like Archive of Our Own (AO3) or FanFiction.net might be good places to start looking for 'percy and echidna lemon fanfiction'. These sites have a vast collection of fan - created works.
One great echidna wars fanfiction is 'The Echidna's Quest' which follows the journey of a young echidna warrior. It has exciting battle scenes and well - developed characters.
In an 'echidna wars snake coil fanfic', it might involve a power struggle. The echidnas, known for their unique spines, could use them as a defense against the coiling snakes. The snakes, on the other hand, with their ability to slither and constrict, might be aiming to overpower the echidnas. It could also include some kind of magic or special abilities within this fictional world that each side uses in the war.
One idea could be that Harry discovers an ancient spell in the restricted section of the library that has the power to summon Echidna. He summons her in a time of great need, like when Hogwarts is under a new dark threat. Echidna, being a mythical and powerful creature, could offer her unique knowledge or abilities to help Harry and his friends fight off the danger.
When Harry summons Echidna, the Hogwarts environment would experience a shockwave of magic. The plants in the greenhouse might wither or grow uncontrollably depending on the nature of Echidna's magic. The House - elves in the kitchen would be on high alert, hiding their precious food supplies. The centaurs in the forest would be conflicted; some might see it as a sign of great change and danger, while others might be intrigued by the appearance of such an ancient being. The Hogwarts faculty would quickly gather to form a protective perimeter around the students, not knowing exactly what Echidna might do.
