I'm not crazy. My reality is just different
When Ferg opened the current into the hole, Sebas shot a ball of darkness, letting the current carry it as far as it needed to go. An explosion rocked the hole, spouting smoke from it. The yells of pain was all the acknowledging he needed. The hole closed and then another one opened a bit of ways away. "We need to get in there! We don't have the mana to play the long game." He swam forward towards the hole and a bunch of Viperfish swam out to intercept him. Taking a few bites, he covered himself in Black Lightning so every fish that bit him died immediately after. It didn't stop the fish FROM biting, just killed them for doing it. As a result, he took quite a few bites, but it ended up killing many of the fish.
"Let's move!" Sebas crossed his arms and the shield projected outwards, blocking any and all fish from any attempts to flank due to the tunnel's narrow size. Adrenaline pumped through his veins from all of the bites. He was beginning to see red and he had to inhale and exhale, needing to find some form of a mental zen before he did what Ferg did but on steroids and go berserk. "Sub! We need information on Dark-Magic induce mazes."
"Requesting information. Standby.............."
"Hurry the hell up, sub!" Sebas yelled and cut off communication.
Before Ferg could follow Sebas into the hole, the hole closed and another opened 10 feet to the right of it, with Sebas nowhere visible within it. This one didn't flood out Viperfish, but there were 2 Fishfolk armed with spears blocking the halfway point of that tunnel
