Short Lore:

In Runetera, natural magic can seem limitless, but lacks direction and purpose. On the other side of the coin of existence, man and creatures have their limits, but have passion and desire.

When the direction and ambition of man can provide the magic of the land with purpose, the results can be terrifying.

In such manner, the Polong was born. From Ionia's natural magics and the catalyst that was the Invasion of Ionia , a vengeful spirit with a thirst for Noxian blood formed, with the help and nurturing of cultists.

Now the Polong roams towards the Noxian walls, formed from the anger, sorrow, murder, and horror caused by the Ionian Invasion.
