While taking a break from my main construction I've been working on some roads and the like. So my short term goal is to try to connect up to the npc village not far from Splat.
In the process of connecting my road with the one that Coralon did off of the network surrounding my main project I decided to do a little exploring when I noticed a cave below the road along to coast.
I was happy to find some nice stocks of coal for my glass floor back home, and then I noticed the edge of a ravine.
Looking down the ravine I saw obvious construction at the end. I thouhg hmm someone must be down there making a home. I decided to trek down the side of the ravine and check it out. As I got closer it became more obvious that this was not made by a player. I actually have never seen a stronghold before in person, but here it was. I did some exploring found a couple small chests and while exploring a side tunnel I saw a single row of stone brick poking through. I dug through and went wow this is a cool room...then the weird little creatures started attacking me. I used some dirt and camped out over a lava pool and got on the wiki to find out what the heck these things were. For the record I don't like silverfish now
After a little bit more exploring I found a reasonably safe room and started digging out to the surface. So now there is a staircase going all the way up to and connected to the main road now.
I placed a few signs and dirt blocks to seal a skeleton spawner and the silverfish room. Other than a couple apples and normal odds and ends I didn't actually get too far into it since need to get to bed for work tomorrow.
But here is a map with the general area marked:
If you follow the main roads out of spawn that leads to or along my construction site you can get there pretty easily. Its really not too far away. Connected to the side of the road is a stone and wood construction with a sign that says Stronghold Entrance. It goes all the way down to a fairly safe room. I also placed a sign in there that should show up on the next map update.
