Perseverance Pays Off
What was a fairly dull and uneventful night of hi-sec exploration eventually paid off just as I was about to call it a night. Till that point I'd only found a few data and relic sites which had yielded about 4m ISK's worth of goodies. Then a Sansha's Watch site presented itself and I was suddenly 190m ISK richer courtesy of a Mid-grade Slave Epsilon implant drop.
On returning to my home system I discovered a Lesser Covert Research Facility which, whilst not yielding any implant blueprints, did drop just under 30m ISK worth of Covert Research Tools and Shattered Villard Wheels.
All in all at the end of the night I was up 225m ISK. I'll take that.
