That means his international signings such as wing Sean Lamont (Scotland) and prop Rhys Thomas (Wales) could be pitted against Lions heroes such as Rob Kearney (full-back) and Jamie Heaslip (No 8).
Davies said: "To have Leinster first up on home turf is a great prospect. Everybody connected with the Scarlets will be relishing the early challenge.
"Anything can happen on day one of the competition and I know that the squad will be up for it in a big way. New players such as Sevens World Cup winner Richie Pugh and stars of the future such as Tavis Knoyle will be eager to get early plaudits.
"With Lions talent such as Brian O'Driscoll and Luke Fitzgerald in the Leinster squad there's a great deal to look forward to on that first weekend in September. We have our own Lions, of course, in Stephen Jones and Matthew Rees and I know our Scarlets supporters will want to give them a warm welcome home after their tremendous efforts in South Africa."
If the round one challenge wasn't enough for the Scarlets, operating under new skipper Mark Jones and vice-captain David Lyons - round three of the championship brings Magners League title holders Munster to Parc y Scarlets.
Davies said: "That'll be another exciting fixture. There were only two points in it when we played them at home in November and we will hope to be in a stronger position than then, with young talent such as Jonathan Davies and Daniel Evans picking up a great deal of invaluable experience last term."
Other stand-out Magners fixtures at Parc y Scarlets include a Christmas weekend cracker against local rivals the Ospreys and a mid-April showdown with the Cardiff Blues.
Davies said: "These are games that our supporters quite rightly look forward to with great anticipation. To have the Ospreys here a day or two after Christmas will make for an outstanding occasion in front of what we hope will be a very large crowd.
"In advance of all this, of course, we have much work to do in pre-season. The group has been back together now for two or three weeks and there's a good feeling and atmosphere around Parc y Scarlets."
