For those who have recently climbed aboard, there are two products here currently for sale.
The most recent one, as you've no doubt seen, is the OSRIC/1E module Secret of Sundance Caverns.
Before that is module 1 of a 6 part megadungeon titled Dread Saecaroth. Parts 2 and 3 are going to be released before summer. Part 1 came in OSRIC or Swords & Wizardry... buyer's choice, but the remainder of the series will be strictly OSRIC. Those who ordered the S&W version and want to continue with the series can contact me at firstname.lastname@example.org and I will give them a freebie OSRIC version.
All products are PDF and can be purchased for $4.99 each via paypal. If you want to pre-order the entire Saecaroth series, you can do so for $30.
