Arcane Language

The language of Arcane, as of Everfest, is known to be as follows.

language-arcane

The Arcane language is often on Runeblade cards and also appeared on the box art of Arcane Rising. The box says:

The shadows, shall rise again, releasing, the arcane, arts once, more.

arcane-rising-booster-box

Runechant tokens contain the arcane language. The text says

Fear not the lightning, fear the darkness that follows.

On the Monarch announcement page we see

I woke in darkness, amongst a ravenous legion. My body birthed from the shadows, my talons forged by the night. And as I grew my hunger too, and the words of the master filled my mind. Child, let's bathe in the blood of the monarch, let's dance on the grave of the light.

At the end of the article Power at any Cost we see the following:

Darkness, Canvas of the Universe.

power-at-any-cost

This also happens to be on the back of cards under the words "Flesh and Blood".

On the mentor card, Lady Barthimont there is a book in the background which states:

"With the rising of the blood, so too does my power wa_ full."
"My will as iron, my words as law, I call unto thee".
