HG's base, part 2

We reappeared a in a small corridor. I could still hear all the noise, so I looked towards one end, and saw fire rush past. 'Where are we?'
'About 300m away. Once that dies down, we pop out that way and head straight for the central chamber.'
'Better get going then.'
'Hang on.'
'Doom had gone over to a door, and was shooting the lock. Remembering we were supposed to be meeting other people, I followed her in, along with everybody else. Doom pressed a button on her watch, and a small red light on it started flashing.
'Ok, they should be here in a moment.'
'Cool. What is that? Where'd you get it?'
'The watch? Our new way of signalling each other. Can't use phones anymore. And let's see, where might I have obtained a TECHNOLOGICAL gadget such as this? Who could I possibly know with enough skill with TECHNOLOGY to make something like this? Hmmm.....'
'Ok, ok, I get it. I made them, but haven't yet.'
I was distracted by movement further in the room. We were in one of those rooms with a pool leading to open water that every base/evil lair seems to have (except us, we should get one of those) with a submarine, small by submarine standards but very big for a one-seater, floating in it. The sub was rocking, as small waves appeared in the water. They rippled across the surface, getting larger and larger, until a swirl started to form. It became a vortex of water, spiraling slowly into the air. A figure leapt out of it at the same moment there was a flash of blue light and a large part of a wall erupted inwards. The pieces slowed in the air, becoming coated in a wispy blue aura, and faded into nothingness before they hit the floor. Somebody was standing just outside the gap onto a circle of blue light, arms raised, two fingers pointed towards what had been the wall, both hands surrounded by the same wispy blue energy, but with the occasional black wisp. The circle faded and he strolled in towards us. He had a big black coat, and a wide-brimmed black hat.
'Of the two of you, I'm guessing you're Blackmage?'
'Yup. Nice to see you again, Tempest'
'Ah, no, I'm the one from the past? Surely Doom said? That's why I was guessing which-'
He lifted the brim of his hat and I suddenly saw what he'd meant. Getting a clear look at his face, I recognised him. He was a friend from Uni!'
'Oh! Hey! So you're Blackmage now?'
'Yeah we've both changed since you last saw us.'
Getting the hint, I turned to look at Maelstrom. He was standing at the side of the pool, shaking the water out of his hair. He was wearing some sort of wetsuit. It was shimmering with greens and blues, with faint silvery white, frothy looking swirls and spirals coiling round it. It made him look like his whole body, except hands, feet and head, was made of water, hiding him from sight inside his vortex of water. I'd met him at Uni before aswell!
Once the introductions were done, and we'd caught them up on how it was going so far, They explained that only they had come because there had been problems sneaking everyone in past the guards, and that HG had put in more precautions than we had thought. Jump offered to help, so they told her exactly where everyone else was waiting, and she teleported away.
The rest of us went back out to the corridor, and, seeing the flames had died down, started to head for the central chamber. We all seemed calmer now, like we knew that, whatever happened, this was it. Behind that door ahead of us, he was waiting. Hooded Guy. Nothing could stop us now....
Guards poured out of every sidedoor, huge numbers streaming out, taking aim. Maelstrom started to spin on the spot, Water appearing from thin air around him as he came a huge, writhing vortex of water, surging down the passage and sweeping away any guard in his way. The circle of light reappeared as Blackmage adopted a battlestance, hands beginning to give of wisps of power again. Bullets rained down on him, but turned to butterflies as the blue aura swept over them. A guard started giving glowing with the fog like energy, black streaks growing to consume him, turning him to stone. We all started fighting with everything we had, and I wondered, not for the first time, quite how many guards HG had. He seemed determined to make sure we didn't make it to that chamber. That means he's scared. He should be.
