Blade Runner is a really great 1.2.3 Minecraft seed. To begin with you get an NPC village near where you spawn. The village is at X: 250 Z: -234 and there is a cave system under the village where you can find lots of coal and iron ores.
A second smaller village can be found at X: 628 Z: -965 it is near a jungle biome with lots of animals nearby.
There is also a stronghold not too far from the first village, it is due East but a little tricky to find since you have to dig rather than follow a cave system. To find it head to X: 914 Z: 78 the last image in the gallery.
Now dig where I placed the torches in the second last gallery image and you will land in the stronghold.
