Terraria – this red glowing thing I’ve found in Terraria

terraria

I just started playing Terraria, so forgive me if this is obvious. When mining, I found a cave with water, and at the bottom of the pool I found this strange red glowing block.

enter image description here

I don't think it's crimtane, as (correct me if I'm wrong) it only spawns in Crimson biomes. Could someone tell me what this is? I can't mine it, but I'm using a "candy cane pick" I found in my inventory. (Guessing christmas)

That's a Crimson Altar, the crimson alternative to the Demon Altar.

It's used as a crafting station to make most pre-hardmode boss items, and Night's Edge.

If you attempt to break it before defeating Wall of Flesh or with a hammer of lesser quality to the Pwnhammer, it will damage you for half of your health.
